Washington is a state in the Pacific Northwest region of the United States located north of Oregon, west of Idaho, and south of the Canadian province of British Columbia on the coast of the Pacific Ocean. Named after George Washington, the first President of the United States, the state was made out of the western part of the Washington Territory, which had been ceded by Britain in 1846 in accordance with the Oregon Treaty in the settlement of the Oregon Boundary Dispute. It was admitted to the Union as the 42nd state in 1889. Olympia is the state capital. Washington is sometimes referred to as Washington State or the State of Washington to distinguish it from Washington, D.C., the capital of the U.S., which is often shortened to Washington.
